Title: Apparatus for automatically adjusting the stitch pitch of a sewing machine
Inventor: GOTO SUMIO
IPC: D05B27/22
Filed: 1985-10-24
Abstract: A stopping apparatus for a sewing machine allows the last stitching point to be positioned at a predetermined point. During stitching, when a photo sensor detects the end of the workpiece, an electronically controlled apparatus adjusts the stitch pitch by detecting the deviation between the needle hole and the last stitch point. A disc with slits circumferentially on its furace is pivoted along a main shaft (2) of a sewing machine; thus the deviation is signalled. The signal causes a stepping motor (18) to rotate and thus a cam (17) pivoted along a main shaft of this stepping motor is also rotated. At the last stitch or two or three stitches before the last, a solenoid (16) acts to pull a feed adjuster lever until it contacts with said cam, thus the stitch pitch is adjusted. The number of stitches needed to finish the stitching after the photo sensor has detected the end of workpiece is operated through a CPU system. Thus, when the counter has counted said number, the machine stops automatically. <IMAGE>
Patent GB-2166546-A (GB)
Title: Apparatus for flue gas analysis
Inventor: FENTON JOHN PAUL CHRISTOPHER
IPC: G01N1/22
Filed: 1985-11-04
Abstract: A sample of hot gas is channeled from a flue (1), via a flow pipe (3) to a gas analyser unit (5) having a thermally insulating casing (13). Upon entering the analyser unit (5), the gas sample is cooled as it passes through a heat exchanger section (16), from which heat is extracted by a Peltier cell (20) and then disipated by a finned radiator (21). The gas sample passes from the heat exchanger section (16) to a gas analysing section (17), and is then returned to the flue (1) via a return pipe (6). The relative positioning of the Peltier cell (20), heat exchanger section (16) and gas analysing section (17) is such that the gas analysing section (17) is at a higher temperature than the heat exchanger section (16). This prevents water condensing from the gas sample after it has left the heat exchanger section (16) and thereby ensures that the atmosphere in the gas analysing section (17) is not saturated with water. <IMAGE>
